Be-it known ithat IglVrLnrait Wis a citizen of f'the United States,residing at St.

7 J osepli in the county-of Buchanan and estate of Missouri, haveinvented certain new I accomplish my objects by the construc tion shownin the accompanying drawings,

in which-e l Figure-1 is a perspective of 'the improved track joint;Fig. 2 is a cross section of the device shown -cut 0n line of Fig. 1;

Fig 3, is across section of the same. showiit -cut-on line y-y of Fig.1; Fig'. 4 is across section of the same, cut on line 2 2 of Fig. 1, andFig. 5 is an enlarged detail'view showing the interior o'fa lockreceptacle-and the lock construction.

Part way. along said groove the walls 6 e thereofremain the height and form a part of the tread of the rail; said wallsare then reducedin height. forming walls 6' e. The inner end of grooveE,as shown in'Fig. 1" is widened forming :1 look receptacle E each sideincut forming a reversed L, asillustrated in Fig. 5 and by dotted linesin Fig. 1.

In

laying said1 rails the inner end of interlock- .ing rail H 'sdroppedintochannelE it'send in contact with the part of rail D that't'orms theclosed end-of said groove; it is then fit snugly in the reversed Jincut. The space left thereby allows for expansion andi the insertion,loosely, of a thin retaining block P, which assists 'in holding thejoint in locked posit-ion.

It will he understood that either or both of the means described forholding the joint sections being broken partly at three sepa rate pointsin addition to the locked ends.

All the joints are made precisely alike and each rail-has a receivingend and an inter-- l-q -rking end by which the track rails can bevonnc'zed at either end. By reason of this feature alone the lowering ofjoints from the pressure of passing trains is wholly ob- What I claimand desire to secure by Letters Patent, is*

1. A track joint comprising the ends of two abutting rails, bases and aflanged plate therefor, the abutting end of one rail end provided with agroove, a lock receptacle at the inner end of said groove, sections ofWalls of differing height forming stops, the other rail abutting againstthe stops formed by said lower walls, its tread resting on said wallsand engagin with the stop formed by the higher Walls, t e narrowed partof said rail beneath the tread housed in said groove, a narrowedextension of the interlocking rail fitting into theinner end of saidgroove,

a locking receptacle at thefend of said interlocking joint, a widenedbossed lock end of said interlocking rail engaging withfsaid'receptacle, a block to retain said lockin partwhen drawn back into seatsforithe osses and a plug block and key-t0 engage with slots in saidhigher-'wallsfland the 1nterloeking rail joint.

2. A track joint comprisin a receiving rail provided'with a groove beween sections of opposite higher and lowerwallsl the latter providedwith corresponding slots, aninterlocking rail having rabbeted sides, abase integral with each rail, the ends of the upper walls abutting andconstituting a part of the track joint, the inner abutting endsof saidlower walls of the receiving rail and the rabbeted sides of theinterlocking rail'constituting a second part of the track joint, theinner abutting end of the sides ofthe tread of the interlocking rail andthe ends of the tops of said higher walls of the receiving railconstituting an additional division of said track joint, a lockreceptacle at the end of said groove, reversed L shape bosses on thesides of the inner end of the interlocking rail, seats in the sides ofsaid receptacle, a loose block in said receptacle to assist in retainingsaid interlocking rail in its seated position and allow for expansionand contraction, and a plug and key to engage with said COIIQSPOIIdIIIslots and serve as a lock complementary to said track joint divisions.

3. In a device of the kind described the combination with a receivingrail having a groove with a widened inner end forming a lockingreceptacle, and duplicate reverse t. shaped bosses on the sides of theend of an interlocking rail adapted to engage with said recesses whenthe interlocking railhs drawn backward thereby locking the railstogether,and a loose bloekinserted in said receptacle -to prevent saidbosses escaping from the same.

4. A track joint comprising a receiving rail having a central groove itsouter wide end forming a locking receptacle with re versed L seats atthe sides, ,an interlocking rail'having bosses on the sides of its endto engage with said reverse L'iseats, sides of section. of theinterlocking rail tread supported on said lower walls-of the receivingrail the ends of said sides abutting with the ends ofthe top of saidhigher Walls forming a partial track joint, the stops formed by the endof'the receiving rail abutting with rabbeted'right angles in the sidesof the interlocking rail forming a second part of the track joint, thecontacting bases of said re ceiving and interlocking rails constitutinga third division of said traclzjoint.

In testimony whereof I afiix my signature in presence of two, witnesses.
